Theoreticians show which quantum systems are suitable for quantum simulations

A joint research group led by Prof. Jens Eisert of Freie Universität Berlin and Helmholtz-Zentrum Berlin (HZB) has shown a way to simulate the quantum physical properties of complex solid state systems. This is done with the help of complex solid state systems that can be studied experimentally. The study was published in the renowned journal Proceedings of the National Academy…

A nice day for a quantum walk

Researchers at the Center for Quantum Information and Quantum Biology at Osaka University used trapped ions to demonstrate the spreading of vibrational quanta as part of a quantum random walk. This work relies on their exquisite control of individual ions using lasers, and can lead to new quantum simulations of biological systems. …

Charting a course toward quantum simulations of nuclear physics

In nuclear physics, like much of science, detailed theories alone aren’t always enough to unlock solid predictions. There are often too many pieces, interacting in complex ways, for researchers to follow the logic of a theory through to its end. It’s one reason there are still so many mysteries in nature, including how the universe’s basic building blocks coalesce and form…

3-D trapping of Rydberg atoms in holographic optical bottle beam traps

Researchers at CNRS, Université Paris-Saclay in France have recently demonstrated the 3-D trapping of atoms in a Rydberg state inside holographic optical bottle beam traps. Their demonstration, outlined in a paper published in Physical Review Letters, could have important implications for the future realization of quantum simulations. …

Ultrafast quantum simulations: A new twist to an old approach

Billions of tiny interactions occur between thousands of particles in every piece of matter in the blink of an eye. Simulating these interactions in their full dynamics was said to be elusive but has now been made possible by new work of researchers from Oxford and Warwick. …
